Why my DecodingError.dataCorrupted? I dont see any reason!

[saroar]

I love this SPM but having also lots of pain after I am using this :(

my model

public struct UserGetObject: Codable {

    public var id: ObjectId
    public var fullName: String
    public var phoneNumber: String?
    public var email: String?
    public var role: UserRole
    public var language: UserLanguage

    public init(
        id: ObjectId,
        fullName: String,
        phoneNumber: String? = nil,
        email: String? = nil,
        role: UserRole,
        language: UserLanguage
    ) {
        self.id = id
        self.fullName = fullName
        self.phoneNumber = phoneNumber
        self.email = email
        self.role = role
        self.language = language
    }
}

public let usersRouter = OneOf {
    Route(.case(UsersRoute.user)) {
        Path { Parse(.string) }
        userRouter
    }

    Route(.case(UsersRoute.update)) {
        Method.put
        Body(.json(UserGetObject.self))
    }
}

// reducer
case .nameForm:
        withAnimation { state.selectedPage = .schaduleForm }

        var currentUser = environment.currentUser
        currentUser.fullName = state.name

        return .task { [cuser = currentUser] in
            return .userUpdate(
                await TaskResult {
                    try await environment.userClient.update(cuser)
                }
            )
        }


// Clinet
public struct UserClient {

    static public let apiClient: URLRoutingClient<SiteRoute> = .live(
      router: siteRouter.baseRequestData(
          .init(

              headers: ["Authorization": ["Bearer \(accessTokenTemp)"]]
          )
      )
    )

    public typealias UserMeHandler = @Sendable (String) async throws -> UserGetObject
    public typealias UserUpdateHandler = @Sendable (UserGetObject) async throws -> UserGetObject
    public typealias UserDeleteHandler = @Sendable (String) async throws -> Bool

    public let userMeHandler: UserMeHandler
    public let update: UserUpdateHandler
    public let delete: UserDeleteHandler

    public init(
        userMeHandler: @escaping UserMeHandler,
        update: @escaping UserUpdateHandler,
        delete: @escaping UserDeleteHandler
    ) {
        self.userMeHandler = userMeHandler
        self.update = update
        self.delete = delete
    }
}

extension UserClient {
    public static var live: UserClient =
    .init(
        userMeHandler: { id in
            return try await UserClient.apiClient.decodedResponse(

          ).value
      },
      delete: { id in

          return try await UserClient.apiClient.data(
            for: .authEngine(.users(.user(id: id, route: .delete)))
          ).response.isResponseOK()

here are example project I create

Hi @saroar, I'm converting this to a discussion because it's not clear it's an issue with the library.

Also, the project you attached doesn't seem to do anything. There are no tests and there is no UI. In order for anyone to be able to help it would be best for you to distill the essence of the problem into a standalone project with no dependencies other than the swift-url-routing library.
